IMPROVEMENT IN ,PAPER-PRESSES.

Specification forming part oi'lietters latenth'o. 40,336, dated Ortober 20, 1603,; antcdatcd October ll, 1863.

To all whom, it nee/y concern..-

lle it known that I, Var. 1t. DINGMAN, of the town of Stuyvesant, in the county of Columbia and State of New York, have invented a new and uscful'machine'for combining and facilitating the operations of pressing and tying paper into reams or bundles, which I call the Combination Paper-Press and Tying- Engine." and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annejved drawings, making a part of this specification, in which- Figure 1 is a perspective view; Fi 2, a front elevation, andFig. 3 a plan or birds-eye view.

Letter A is the franie of the press; B, the vertical sliding frame; 0 0, guide beams; I), hand or capstan wheel; E, hand-wheel shaft; F, crank-shaft at right angles to G 2, crossbeams supporting the bevel'gear; H, connect ing-rod or pitman; I, crossbeam secured to frame A for supporting the lower jaws or bedplates of the press; J J J J J, metallic plates or jaws forming lower part or bed of the press; K, crossbar secured to the sliding frame B, and provided with journals at each end L L L L L, plates orjaws supported by the metallic rods 7.- 7: k 7; 7:, forming the'upper or active part of the press; M, ratchet-wheel secured to handwheel shaft, N, pawl to hold the 'press while the paperis being tied; O, yoke-bar; 1, spring to operate yoke-bar; c, bevel-pinion on end of shaft 1); f, bevel-gear wheel on end of crank.- shaft I worked by pinion e,- crank secured to end of crank-shaft I1, and connected with and operating the sliding frame B by means of the connect-ingrod II 1 i i it, metallic stand ards supported by cross-beam I; k 7.: 7; 7; 1;, metallic standards supported by cross-bar K in sliding frame 13.

To enable those skilledjn the art to make and use my invention, I will proceed to describe its construction and operation.

The frame A may be made of hard wood or metal of any required dimensions. For common straw wrapping-paper I use one which is three feet long by two feet wide and three feet in height. These proportions as also the size of the press, may be varied, as required.

IVithin the franieAis placed the transverse sliding frame B, of such breadth as to slide easily up and down in the guide-beams O G. This sliding frame is operated by the hamlwheel D. I will here suggest that this hand- .gles to shaft E.

To the end of shaft F is secured the crank 1 by means of which and the connecting-bar H, the sliding frame I; is operated. This connecting-bar is adjustable, its length being varied by having holes at different distances from the crank-pin, through which. the bolt connecting its lower end with the lower crossbeam of the slidiiig'frame may be inserted. On this bolt the connecting rod or bar II is of course movable can vibrate or revolve freely as the sliding frame moves up and down. At its upper end this connecting-bar is connected with the crank 1/ by a bolt on which the latter rcvolves, forming a toggle or hinge joint. The combined length or angle of connection of crank and connecting-rod may thus be varied to correspond with the degree of pressure requircd.

To the beam I, which is bolted firmly across the frame A, is secured a series of metallic standards 1' i i 2' 17, supporting metallic plates J J J J J' at their upper ends, which form the lower half or bed of the press. To the cross bar of the sliding frame B is also secured another seriesof standards 7; 7; k I. k, which extend up behind and a little above the former, and to which are attached the corresponding plat-es, L L L I. L, forming the upper jaws or active part of the press. These plates are separate, and snl'liciently disconnected to allow the string or cord used for tying the paper to pass between.

I would suggest that the operation of this press may be varied by making the pressure upward instead of downward; but I do not think it advisable. The cross-bar K is provided with journals at each end, so as to allow it end-play. The yoke-bar O, which in its ordinary position. rests against the standards k k 7.: 7.: 7;, and keeps them upright and in place when it is thrown back against the spring 1?, allows the standards when elevated to drop back, the bar K rolling on its journals, so as to make the space between the upper and lower jaws larger, if required. \Vheu the standards begin to descend with the sliding frame, the yoke-bar comes in contact with the spring I, which throws it over against the standards and forces them back again into their original upright position. The pawl N is employed upon the ratchet-wheel M to hold the press while the paper is being tied. After this it is removed, and, if necessary, is cut into ordinary or single crowitreams. The spring I? is secured to the crossbeain G. (See Fig. 3.)

The operation of my press is evident from the foregoing description of its construction. By means of the hand whccl 1.), operating the bevel-gears a f,the crank and the connecting-rod H, the sliding frame .13, carrying the rolling-bar K, with the standards k l.- 7.- 7.: I; and their several jaws, are elevated. The loose paper, in sheets or bundles as it comes from the machine, is deposited'on the lower jaws or bed of the press. This being done, the handwheel is revolved backward toward the operator, causing the jaws L L L L L to descend upon the paper and to compress it to the degree required. The pawl X, being hooked, drops into the ratchets on wheel 31 and holds the press down until the paper is tied. By a reverse movement of the hand-wheel, the pawl being raised, the pressure is relieved and the paper removed.

The process of pressing and tying paper now generally employed requires a large and somewhat expensive press, which is located in some corner of the finishing-room, and as the paper comes from the machine it is carried to the finishing-table, there counted and folded, and when snliicient is obtained to till the press (usually about one hundred reams) it is conveyed'to the press and placed therein, and, by means of a large screw and follower, pressed for about twelve hours, or during the night. It is then removed and conveyed to the tie-table and .there tied into reams. After this it being, when it comes from the machine, usually double-crown, or double the length of the ordinary ream of wrapping-pa per) it is cut into two reams or single-crown. The usual mode of tying paper is by passing a strong cord or twine around the ream, with a noose or loop at the end, through which the other end passed and then drawn upon with the hand until the loose ream or bundle is sulliciently compressed. This operation is laborious and tedious, occupies much time,

requires strong twine, and unavoidably draws the ream away or the paper out of place.

The following, on the other hand, are some of the advantages I claim for my press and my mode of tying:

First. It combines in one machine both the press and the tie-table, and occupies much less space than the old press alone, and can be easily conveyed from place to place, to suit convenience.

Second. It efi'ects a great saving of time and labor, requiring no longer to take the paper from the finishing-table, press, and tie it in this machine than it does to remove it from the ordinary press to'the tie-table alone. The tying process with my press, instead of being laborious, is simple and easy, requiring comparatively light cord or twine, and leaves the ream perfectly square.

Third. The paper is pressed uniform in thickness, and no part of the ream can be moved out of its place by the process of tying, since it is held firmly while this is being done.

Fourth. Ordinarily, new, a full press of paper is made before any partof it is pressed. \Vith my machine it can be nessed about as fast as it is made, so that it need not lieloose about the mill and be wasted, as it often is in the ordinary process.

Fifth. Instead of requiring a man, as it does for the old process, effecting comparatively little work, a boy, or even a girl, is suiiicient to press and tie with my machine, and does more work and does it better.

\Vhatl claim as my invention, and desire to secure by Letters Patent, is-

1. Constructing and employing a press with a series of jaws or corresponding upper and nether metallic plates, .7 .T J J J and L L L L L, all disconnected, so that while the paper is being subjected to the required pressure it may be easily tied into reams or bundles.

2. The arrangement of the standards 7. 7. Ir 1. 7.: with their plates L L L L L operating in combination with '2' i 1' I i, with their respective plates J J J J J, substantially in the man ner and for the purpose herein set forth.

3. The combination and arrangement of the several parts and devices employed to operate the sliding frame 13, or their cquivalents,substantially as and for the purpose herein set forth.
